Reason:
Imagine a table with 4 rows and 9 columns.
The 4 rows represent the number of pants.
The 9 columns represent the number of shirts
Each row/column combo is a different pants+shirt outfit.
The 4 by 9 table has 4*9 = 36 items total.
The table itself is optional, and can be done as a thought experiment. The only steps you need to show really is 4*9 = 36.
